INSERT.

Application filed April 26, 1922. Serial No. 556,597.

useful Improvements in an Insert, of which the following is a specification.

My invention relates to hanger inserts and particularly to an improvement on the construction shown in my co-pending application, 'Ser. No. 464,879, filed April 27, 1921. This application is a continuation in part of my co-pending application Ser. No. 510,131, filed Oct. 24, 1921. 7

One of the objects of the present invention is to provide a device of the class described, the construction and operation of which is much simplified. One of the essential points of advantage in the present construction is in the provision of a separate fastening staple frictionally held in position and so shaped as to facilitate driving without the attendant disadvantages of constructions heretofore proposed. Another advantage is in the constrution of the casing or housing for receiving the ring or hanger. By modifying the construction of the fastening staple I am enabled to provide a housing of simple form adapted to be cheaply made from dies and readily assembled.

A further advantage in the construction shown is in that I may employ a heavy wire or rod for the supporting element and a light wire staple for securing the device in position. Thus there is. less difficulty in positioning the device and lessdanger of splitting the form-boards in driving the staple. Ample holding capacity may be secured by employing a staple of smaller gauge wire than could be used for anchoring the hanger in the concrete.

An additional advantage in the construction shown is in that the staple employed provides driving points which are close together relatively and there is less danger of improper application of the insert'than in any construction in which the driving points are Widely separated. V r

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Fig. 1 is a side elevation of a hanger insert constructed in accordance with my invention;

Fig. 2 is a sectional View on the line 22 of Fig. 1;

Fig. 3 is a plan view;

Fig. 4 is a perspective view of the housing in its assembling position;

Fig. 5 isa perspective view of the fasten-- ing staple employed;

Fig. 6 is aside view of a slightly modified form in which a tapped nut is held within the housing;

Fig. 8 is a side view of a further modification of the invention in which the device adapted for use as a pipe hanger, and,

Fig. 9 is a sectional view. taken'at right angles to that of Fig. 8.

In the drawings and referring particularly to Figs. 1 to o-inclusive, it will be seen that I employ an anchor member consisting of a heavy wire bent .to provide a loop 10, P

and terminal loops or rings 11, constituting anchoring ears. engagement with the loop 10, and is adapted for vertical movement to the extent indi cated in Figs. land 2. A housing of sheet metal is provided, it including parallel side walls 18, 14, the walls 13 having grooves 15. pressed therein to accommodate the side members of the loop 10. The side walls 14 are extended upwardly beyond the walls 13 and the projecting, portions 16, 17,. are adapted to be bent downwardly and overlapped, the part 17, having a lateral flange 18, which overlies the side wall. The marginal edges of the strip of metal composing the side walls are overlapped as at 19. and may be joined by welding. if desired, .al though this will be found to be unnecessary in'practice. i

The hanger, as already. described, is complete so far as its function of serving as an anchored hanger-is concerned, the housing defining a space from which the concrete is excluded and within which the hanger loop 12 is received. However, I provide a simple fastening device consisting of the stapleQO, the legs of which straddle the housing and fit snugly alongside of the deflected portions of metal constituting the grooves15. The staple may be of light gauge wire of sufli: cient strength .to securely holdthe hanger A flattened ring 12 is in inposition and the legs of the staple will i placing of the insert, this for the reason that the insert may be rested squarely on the form before being secured in place, the staple being pushed upwardly into the dotted line position of Fig. 1. Thereafter the staple may be driven without difficulty and without danger of uneven or faulty location of the insert.

In operation the parts are assembled as shown in Fig. 1. When the insert is to be applied to a form it is rested thereon with the ring in the elevated position shown. After the staple has been driven the concrete is. poured therearound. After the form is strip ed tie projecting ends of the staple may be clipped if desired but this will be unnecessary so far as the functioning of the hanger loop is concerned.

In the construction shown in Figs. 6 and 7, the anchor member is the same consist.- ing of loops 21 and 22, the loop 21 engaging the eye '23, formed on a rectangular metal block 24, having a tapped opening 25 therein. The metal block or nut is adapted to be held securely within a housing 26, identical with that shown in Fig. t. A fastening staple 27 is employed, which functions in the same manner as that described in connection with the construction shown in the preceding figures. The device is similar in all of its characteristics to that heretofore described except in that a tapped nut is substituted for the flattened ring.

The construction shown in Figs. 8 and 9 is likewise the same in all material respects except as to the form of the slidable depending member. This element, lettered 28, is a flat strip bent into U-shape, the closed end of the loop engaging the depending portion 29 of the anchor wire. The open end of the Ushaped loop is closed by a transverse short bolt 30, which passes through registering apertures in the legs of the loop and serves to support a hanger strap 31, of common form. The apertures 32 in the strap are arranged in spaced relation and a selected aperture is engaged by a pipe-supporting band in the usual manner. This is a very convenient and useful adaptation of the device where sprinkler systems are to be installed in concrete buildings.

Obviously other modifications may be made than those shown and I do not wish to be limited except as indicated in the-appended claims.

I claim:

1. In a hanger, the combination of an anchor, a housing surrounding a portion thereof, and ,a separate staple straddling said housing with the points projecting beyond the limits of the same.

2. In a hanger, the combination of a rod bent to provide a looped portion and laterally deflected ends, a housing for said looped portion, and a separate staple straddling said housing with the points projecting be yond the limits of the same.

3. In a hanger, the combination of a rod bent to provide a looped portion and lat erally deflected ends, a housing for said looped portion, and a separate staple straddling said housing with the points projecting beyond the limits of the same, the legs of the staple frict-ionally engaging the sides of the housing with capacity for sliding movement -hmgitudinally of the staple.

4. In an insert, the combination of a member bent to provide a 1001) having parallel portions and laterally deflected ends, a housing cooperating with said loop and having lateral grooves for accommodating the parallel portions of said loop, and a staple adapted to overlie, and the legs of which frictionally engage the casing adjacent to the offset metal which forms said lateral grooves.

In a hanger insert, the combination a rod bent to provide a depending loop and ends forming lateral terminal portions, a housing to receive said looped portion and having a closed upper end and a sep arate fastening device comprising a staple adapted to fit over said housing with its legs in contact with the sides thereof and with its points normally projecting below the plane of the open end of said housing.

6. In a hanger insert, the combination of a rod bent to provide a depending loop and ends forming lateral terminal portions. a housing to receive said looped portion and having a closed upper end and a separat fastening device consisting of a member frictionally held in engagement with said housing whereby said housing and anchor-- ing device may be placed in position in contact with a form and said fastening device driven into place.

7 In a device of the class described, the combination'of an anchor including a loop, a housing surrounding said loop, a separate staple straddling said housing with the points projecting beyond the limits of the housing, and a vertically slidable hanger adapted to engage said loop.

8. In an insert, the combination of a housing, means for anchoring the same in concrete, a hanger within the housing, and a separate staple straddling the housing with the staple points adapted to project beyond the lower limits of the housing.
